<div class=slotDescription>
To start debugging a coroutine, call
	<code>
	Coroutine currentCoroutine setMessageDebugging(true)
	</code>
	Then each message sent within that coroutine will cause the Debugger 
	vmWillSendMessage slot to be activated and the Debugger slots: 
	messageCoroutine, messageSelf, messageLocals, and message will be set with the 
	values related to the current message send. You can override vmWillSendMessage to 
	implement your own debugging mechanisms.

<a name="Debugger-start"></a><b>

<div class=slotDescription>

vmWillSendMessage

<p>
<div class=slotDescription>
Override this method to implement your own debugging mechanisms. Default behavior is to print every message sent.
